Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simulator for expressing a simulated operation by an expression means such as a display corresponding to the operation of an operator. In particular, the present invention relates to a simulator that expresses a simulated operation by an expression means corresponding to the movement of a support base that rotates and moves when an operator rides. In particular, the present invention relates to a locking device for holding the rotating support base in a fixed state, that is, in a locked state.
[0002]
[Prior art]
As a conventional simulator, there is known a ski game apparatus in which an operator rides on a board simulating a ski board and performs a pseudo skiing operation. In particular, recently, a ski game apparatus using a board simulating a ski as an input means, performing a virtual skiing operation, and displaying the state on an expression means such as a display is also known.
[0003]
In such a ski game apparatus, the board that supports the operator may turn in a horizontal plane, or the left and right sides of the board may tilt up and down around the central axis passing through the center of the board. Assuming that the rotational movement of the board, such as swivel movement and tilt movement, is always performed freely without any restriction, the board will swing unstable when the operator gets on and off the board. There is a possibility that a large load is applied to the support mechanism of the board and the board is damaged.
[0004]
[Problems to be solved by the invention]
In order to solve the above-described problems, conventionally, when a simulation such as a ski game is finished, the board is fixedly held, that is, locked. However, in the conventional lock device, the locked state and the unlocked state with respect to the board are switched instantaneously. Therefore, when the operator unlocks the board after getting on the board, the board is suddenly released, and the board suddenly swings, which may cause a large load on the support mechanism and the like. Further, when the board is locked again after the ski game or the like is finished, the board is suddenly switched from the unlocked state to the locked state, so that a large load is easily applied to the support mechanism and the like.
[0005]
The present invention has been made in view of the above-described problems, and it is an object of the present invention to prevent a large load from being applied to a support mechanism of a support base when the operator gets on and off the support base such as a board. .
[0006]
[Means for Solving the Problems]
A simulator locking device according to the present invention has a support base that rotates when an operator rides and operates, and is used in a simulator that expresses a simulated operation by an expression means corresponding to the movement of the support base. The locking device is a locking device for fixing and holding the support base, and has a locking force applying means for applying a locking force to the support base. Grant The means gradually weakens the locking force over time when the state of the support base is changed from the locked state to the unlocked state, and the lock force is changed over time when the state of the support base is changed from the unlocked state to the locked state. The cam member is fixed on the rotation center axis of the support base, and the locking force applying means applies the locking force to the support base via the cam member.
[0007]
In this locking device, the rotational movement of the support base is prohibited when the locking force is the maximum value, and the free rotational movement of the support base is allowed when the locking force is the minimum value. When the locking force is switched from the maximum value to the minimum value, the magnitude gradually decreases with time, and when the locking force is switched from the minimum value to the maximum value, the magnitude gradually increases with time. Become stronger. As a result, the fixed state of the support base on which the operator is riding does not suddenly come off or go in, but gradually comes off or goes in gradually. Accordingly, since the support base does not swing suddenly when the operator gets on and off, a large load is not applied to various mechanisms around the support base, thereby improving durability.
[0008]
In the above description, “rotating support base” means that the support base swivels in the horizontal direction in the horizontal plane, or the support base reciprocates around the horizontal axis at the center. It is.
[0009]
The shape of the support base is not limited to a specific shape, and is an appropriate shape corresponding to the target simulated operation. For example, when simulating the sliding of a snow surface by a snowboard, it is shaped like a snowboard.
[0010]
The expression means is means for enabling an operator to visually recognize an arbitrary simulated action, and the expression method is not limited to a specific method. For example, a display that displays images or a doll model that displays realistically can be used.
[0011]
The locking force applying means can be configured using a hydraulic cylinder, a pneumatic cylinder, or any other force generating device. However, in order to easily achieve the function of gradually changing the size of the lock force, it is advantageous to use a hydraulic cylinder. Specifically, the locking force can be adjusted by adjusting the flow rate of the oil flowing in the hydraulic cylinder. For example, when the oil flow rate is reduced, the locking force increases, and when the oil flow rate is set large, the locking force decreases.
[0012]
The output rod of a force generating device such as a hydraulic cylinder can also be brought into direct contact with the support base, but in that case, the space for installing the hydraulic cylinder or the like is limited to a specific position. In order to solve this problem, a contact piece that moves so as to come into contact with or leave the support base may be newly provided, and a locking force may be applied to the support base via the contact piece by a hydraulic cylinder or the like. Since the hydraulic cylinder or the like only needs to apply a locking force to the contact piece, the installation position of the hydraulic cylinder or the like can be freely set by appropriately selecting the shape of the contact piece.
[0013]
A force generating device such as a hydraulic cylinder may be configured to apply a locking force to the support base via a cam member fixed to the rotation center axis of the support base instead of the contact piece.
[0014]
When transmitting a locking force from a hydraulic cylinder or the like to the support using the contact pieces that contact the support, it is desirable to dispose the contact on both sides of the rotation center axis of the support. If the contact piece is disposed only on one side of the rotation center axis of the support base, it is difficult to place the support base in a stable locked state on the side where the contact piece is not installed.
[0015]
When the contact pieces are arranged on both sides of the rotation center axis of the support base, the pair of contact pieces are integrally connected by a connecting shaft, and the locking force applying means is installed on one side of the pair of contact pieces. It is desirable to do. This is because the pair of left and right contact pieces can be driven integrally by a single locking force applying means. Further, according to this configuration, since the pair of left and right contact pieces move integrally, the support base can be accurately held in the locked state at the horizontal position.
[0016]

In the present embodiment, the first rotation center axis L1 is a vertical axis, and the second rotation center axis L2 is a horizontal axis.
[0017]
In the case of the present embodiment, it is assumed that on the display 1, a skiing landscape image and a video of a player sliding on the snow surface using a snowboard are displayed. Further, the support base 7 is formed in a shape simulating a snowboard. In addition, four support columns 9 are fixed around the support base 7 and extend upward. By these support pillars 9, the front and rear of the operator 8 riding sideways between the operator 8 and the display 1 and on the support base 7 are supported. Handrail members 11 are supported on both sides. These handrail members 11 are formed by relatively rigid rod members. The operator 8 can move the operation table 7 violently by being caught by these handrail members 11.
[0018]
The support base 7 has a structure shown in FIGS. 1, 2, and 3, for example. 1 is a side view, FIG. 2 is a plan view, and FIG. 3 is a front view. In FIG. 1, a rotary shaft supported inside the operation unit 5 so as to be rotatable about a first rotation center axis L <b> 1 but not vertically movable by bearings 12, 12 fixed to a stationary machine frame 14. 13 is disposed, and the arm member 6 is fixed to the rotating shaft 13.

The casing member 16 is fixed to the machine casing 14. The elastic member 17 is formed of a material that generates a resistance force when compressed, such as rubber or synthetic resin.
[0019]
In FIG. 1, a rectangular tube-shaped pipe base 19 is firmly fixed to the lower end of the arm member 6 in a state of extending in the horizontal direction. Bearing members 21a and 21b are fixed on the pipe base 19, and the two rotating shafts 22a and 22b are supported by these bearing members so as to be rotatable about the second rotation center axis L2. A bracket 23 fixed to the bottom surface of the support base 7 is fixed to the outer peripheral surfaces of the rotary shafts 22a and 22b. With this configuration, the support base 7 can reciprocate in the horizontal direction in the horizontal plane (in the direction of the arrow AA ′ in FIG. 2) about the first rotation center axis L1, and further the second rotation center axis L2 It can be reciprocally inclined and moved in the direction of arrow BB ′ in FIG. 3 as the center.
[0020]
In FIG. 1, a second resistance applying device 28 is provided at the right end of the rotating shaft 22 a on the side close to the operation unit 5. Similarly to the first resistance applying device 18, the second resistance applying device 28 also has a square member 25 having a square cross section integral with the rotary shaft 22 a and a cross section surrounding the core member 25. It has a square and cylindrical casing member 26, and an elastic member 27 as an elastic member inserted in a space formed between the casing member 26 and the core member 25. The casing member 26 is fixed to the upper surface of the pipe base 19.
[0021]
In FIG. 2, the first resistance applying device 18 is in a state where each elastic member 17 is in a mechanical equilibrium when the external force is not applied to the support base 7. At this time, the support base 7 is in the neutral position. Retained. When the support base 7 pivots in the direction of arrow A or arrow A ′, the rotary shaft 13 that supports the support base 7 rotates integrally therewith, and at the same time, the core member 15 rotates together therewith. When the core member 15 rotates, each elastic member 17 is pressed against the casing member 16 and elastically deformed to generate a resistance force. This resistance force changes in proportion to the rotation angle of the rotating shaft 13 and thus the turning angle of the support base 7.
[0022]
When the second resistance applying device 28 is in a natural state in which no external force is applied to the support base 7, the elastic members 27 are in a state of mechanical equilibrium in FIG. 5. At this time, the support base 7 is in FIG. 3. Is held at a neutral position in a horizontal state indicated by a solid line. When the support base 7 is inclined and moved in the direction of arrow B or arrow B ′, the rotary shaft 22a that supports the support base 7 rotates integrally therewith, and at the same time, the core member 25 rotates together therewith. When the core member 25 rotates, each elastic member 27 is pressed against the casing member 26 and is elastically deformed to generate a resistance force. This resistance force changes in proportion to the rotation angle of the rotating shaft 22a and hence the inclination angle of the support base 7.
[0023]
In FIG. 1, a first angle sensor 29 including a variable resistor whose resistance value changes according to the rotation angle of the rotation shaft 13 is provided at the lower end of the rotation shaft 13 that rotates about the first rotation center axis L <b> 1. . A second angle sensor 31 including a variable resistor whose resistance value changes according to the rotation angle of the rotation shaft 22a is provided at the tip of the rotation shaft 22a that rotates about the second rotation center axis L2.
[0024]
A lock device 32 for prohibiting the tilting movement of the support base 7 around the second rotation center axis L2 is disposed below the support base 7. The lock device 32 includes a lock force applying device 33, a lock force adjusting device 34, and a contact piece 35. The locking force applying device 33 includes a hydraulic cylinder, and includes a cylinder main body portion 36, an output rod 37 that enters and exits the main body portion 36, and a pressing piece 38 that is fixed to the tip of the output rod 37. is doing.
[0025]
As shown in FIG. 4, the cylinder main body portion 36 of the locking force applying device 33 includes an outer tube 43, an inner tube 39, and a mover 41. The inner pipe 39 is provided with a plurality of orifices 42, and a piston 45 integral with the output rod 37 slides on the inner peripheral surface of the inner pipe 39. The left end 41a of the mover 41 is screwed to the rear end of the outer tube 43, and the mover 41 moves forward and backward in the direction of arrow C by turning the left end 41a. A ring-shaped space S is formed between the inner tube 39 and the outer tube 43, and the space S and the inside of the inner tube 39 are connected by an orifice 42. The mover 41 is provided with an oil passage 44 communicating with the space S. When the mover 41 moves in the direction of arrow C, the opening area of the oil passage 44 is narrowed or widened, Adjust the flow rate of oil flowing through the section.
[0026]
The inside of the inner tube 39 and the space S are filled with oil as a fluid, and a resistance force, that is, a locking force is applied to the output rod 37 by the action of the oil. This resistance is maximized when the oil passage 44 of the mover 41 is completely closed and the flow rate of oil is completely throttled, while the oil passage 44 is completely opened and the flow rate of oil reaches the maximum flow rate. Minimum when set. When the resistance force reaches the maximum value, the output rod 37 is completely prevented from entering in the left direction, that is, a so-called locked state. On the other hand, when the resistance force reaches the minimum value, the free movement of the output rod 37 in the left direction is allowed.
[0027]
In the present embodiment, when the end 41a of the mover 41 is adjusted to the reference position of 0 °, the oil passage 44 is fully opened (the output rod 37 is unlocked), and the end 41a is up to an angle of 180 °. When turned, the passage 44 is fully closed (the output rod 37 is locked), and the resistance force or locking force against the output rod 37 is proportional to the angle value between 0 ° and 180 °. The size of changes. In addition, the output rod 37 is pushed by the compression spring 40 in a natural state and is in a state of protruding most from the outer tube 43.
[0028]
In FIG. 1, the pressing piece 38 attached to the tip of the output rod 37 contacts the lower end of the contact piece 35. As shown in FIG. 2, the contact pieces 35 are fixed one by one to both ends of a connecting shaft 46 that is rotatably disposed on the pipe base 19. That is, the contact pieces 35 are disposed on the left and right sides below the support base 7 with the second rotation center axis L2 as a boundary. In FIG. 1, when the support base 7 is in a horizontal state, the output rod 37 protrudes most with respect to the cylinder body portion 36 and pushes up the contact piece 35, whereby the tip of the contact piece 35 is at the uppermost position as indicated by a solid line. To the bottom surface of the support base 7. On the other hand, when the support base 7 is tilted and moved around the second rotation center axis L2, the contact piece 35 is pushed down and rotated as indicated by a broken line, and at this time, the output rod 37 is retracted into the cylinder body portion 36.
[0029]
When the output rod 37 protrudes most and the tip of the contact piece 35 is placed at the uppermost position, and the internal oil passage 44 of the locking force applying device 33 is set to the fully closed state, the contact piece 35 is locked at the uppermost position. It becomes. In this state, the support base 7 is in a locked state while maintaining the horizontal state, and even if the operator gets on the support base 7, the support base 7 does not reciprocate, that is, does not swing.
[0030]
In FIG. 1, the locking force adjusting device 34 disposed at the rear position of the locking force applying device 33 includes a rotating shaft 48 rotatably supported by a bracket 47 fixed to a side portion of the pipe base 19, and a motor 49. And a gear train 51 for transmitting the output rotation of the motor 49 to the rotating shaft 48. In FIG. 4, a driver 54 is attached to the tip of the rotating shaft 48, and the driver 54 is fitted to the left end 41 a of the mover 41. Further, in FIG. 1, a wheel 52 having a mark for detecting the rotational angle position is fixedly disposed at an appropriate position of the rotating shaft 48, and transmissive or reflective light is used to detect the mark on the wheel 52. A sensor 53 is provided. In the present embodiment, the wheel 52 is made to correspond to the case where the end 41a of the mover 41 shown in FIG. 4 is at the reference angle 0 ° (fully open position) and at the angle 180 ° (fully closed position), respectively. A mark is provided.
[0031]
When the motor 49 is actuated to rotate the rotary shaft 48 from the fully closed position at an angle of 180 ° to the fully open position at an angle of 0 °, the contact piece 35 and thus the support base 7 changes from the locked state to the unlocked state. When this state changes, the resistance force generated on the output rod 37 by the locking force applying device 33, that is, the locking force, gradually and continuously from the maximum force that realizes the locked state to the minimum force that hardly exhibits a resistance force. It gets smaller. Therefore, when the operator gets on the support base 7 locked in the horizontal state and then releases the lock state of the support base 7 in order to start the simulation operation, the support base 7 instantaneously enters the locked state. The locked state is gradually released instead of being released. With this configuration, the support base 7 does not suddenly swing, so that a large load is not applied to the support mechanism of the support base 7 and the like is not damaged.
[0032]
The above description is for the case where the motor 49 is operated and the rotary shaft 48 rotates from the fully closed position at an angle of 180 ° to the fully open position at an angle of 0 °. The same can be said when rotating from the fully open position of 0 ° to the fully closed position of 180 °, that is, when the simulation operation is finished and the support base 7 is returned from the unlocked state to the locked state. That is, also in this case, the support base 7 does not suddenly change from the unlocked state to the locked state, but gradually changes to the locked state, so that the support base 7 does not suddenly greatly swing.
[0033]
In FIG. 6, the control device 2 installed inside the housing 3 is configured by an electric circuit including a computer, and includes a game calculation unit 61 and an image composition unit 62 as shown in FIG. 7, for example. The operation unit 63 includes various selection buttons 10 arranged on the operation panel 5a of FIG. 1, a coin sensor that detects coins inserted from the coin insertion slot 20, and a first angle sensor that detects the turning angle of the support base 7. 29, a second angle sensor 31 for detecting the tilt angle of the support base 7, and the like.
[0034]
The game calculation unit 61 includes a map information storage unit 64, a moving body information storage unit 65, a game space calculation unit 66, and a storage unit 67. The map information storage unit 64 stores information on the board sliding course as divided map information. That is, the course information is stored as the plane coordinates of each point and the altitude coordinates of that point. The moving body information storage unit 65 stores the current position of the board player in three-dimensional coordinates. The game space calculation unit 66 reads the current position of the board player from the moving body information storage unit 65, and further calculates the movement position of the board player based on the operation signal from the operation unit 63 and the terrain signal from the map information storage unit 64. Then, the movement position of the board player is calculated according to a change in natural conditions stored in the storage unit 67, a change in wind, or the like. The contents stored in the mobile body information storage unit 65 are updated every 1/60 seconds based on the calculation of the game space calculation unit 66 because the display 1 is used as means for displaying the simulated action. The game space calculation unit 66 calculates the position coordinates of other board players displayed on the display 1 as well as the position coordinates of the board player corresponding to the operator riding on the support base 7.
[0035]
The image composition unit 62 includes a three-dimensional calculation unit 68, an image drawing unit 69, and an object image information storage unit 71. The object image information storage unit 71 stores information necessary for creating a video of a course, for example, image information of a moving body such as a board player, image information of a snow surface, a mountain, a tree, a river, a building, and the like. To do. The three-dimensional calculation unit 68 reads the corresponding image information from the object image information storage unit 71 based on the data output from the game space calculation unit 66, that is, the moving body information, the division map information, etc., for example, as shown in FIG. Such a three-dimensional game space is calculated. In this figure, 81 is a board player, 82 is a gate, 83 is a building, 84 is a lift, 85 is a snowy mountain, and 86 is a tree.
[0036]
The three-dimensional calculation unit 68 also performs processing such as clipping processing for removing data outside the field of view, perspective projection conversion to the screen coordinate system, and sorting processing, and outputs the processed data to the image drawing unit 69. . The image drawing unit 69 converts the output data of the three-dimensional calculation unit 68 into video data that can be displayed on the display 1. For example, the three-dimensional game space shown in FIG. 8 is displayed on the display 1 as an image as shown in FIG. This video is updated every 1/60 seconds based on the calculation processing by the game space calculation unit 66, and is recognized as a skiing landscape video that continuously changes for the operator.
[0037]
The operation of the simulator having the above configuration will be described below. In FIG. 1, before the operator gets on the support base 7, the support base 7 is held at a neutral position within the swivel swing range by the action of the first resistance applying device 18, and further the second resistance applying device. By the action of 28, the neutral position within the tilt swing range, that is, the horizontal state is maintained. At this time, the rotating shaft 48 of the locking force adjusting device 34 of the locking device 32 is in the fully closed position at an angle of 180 °, and gives the maximum resistance force to the support base 7 through the contact piece 35, thereby Fixed or locked in a horizontal state.
[0038]
Thereafter, as shown in FIG. 6, the operator 8 gets on the support base 7. At this time, since the support base 7 is in a locked state, it does not swing even when an external force is applied. Thereafter, when a coin is inserted into the coin insertion slot 20 and the selection button 10 is further operated, a simulator operation, in the case of this embodiment, a snowboard game is started. When the game is started, in FIG. 1, the motor 49 of the locking force adjusting device 34 is operated to rotate the rotary shaft 48 from the fully closed position at an angle of 180 ° to the fully open position at an angle of 0 °. As a result, the oil passage 44 (see FIG. 4) in the main body portion 36 of the locking force applying device 33 is gradually opened from the fully closed position toward the fully opened position. As a result, the locking force on the support base 7 is increased from the maximum value. It is gradually released to the minimum value.
[0039]
When the locking force is completely released, the support base 7 can be freely reciprocally tilted about the second rotation center axis L <b> 2 according to the operation of the operator 8. When releasing the locking force, the locking force is not instantaneously released from the maximum force to the minimum force, but gradually decreases with the rotation of the rotating shaft 48 of the motor 49. It does not become a state where it can be freely tilted with the start of the game, but gradually shifts to that free state. In the case of the present embodiment, since no locking device is provided for the reciprocating swiveling movement of the support base 7 around the first rotation center axis L1, the support base 7 is not locked in the turning direction. In the case where the locking operation is required also in this turning direction, a locking device similar to the locking device 32 is attached to the rotating shaft 13.
[0040]
After the locked state of the support base 7 is released, an image simulating the change of scenery when sliding down the ski area is displayed on the display 1 so that the operator 8 can successfully slide down on the snowboard in the scenery. The support 7 is operated with both feet. Specifically, the support base 7 is swung around the first rotation center axis L1, or simultaneously tilted around the second rotation center axis L2. At this time, the angle of the turning movement and the angle of the inclination movement of the support base 7 are detected by the first angle sensor 29 and the second angle sensor 31 and sent to the game space calculation unit 66 (FIG. 7). The game space calculation unit 66 controls the scenery video and the board player video displayed on the display 1 based on the angle information. Thus, the operator 8 can actively work on the sliding screen expressed by the display 1, that is, the simulated operation, by turning and tilting the support base 7.
[0041]
When the support base 7 pivots around the first rotation center axis L1 and angularly deviates from the neutral position, the elastic member 17 in the first resistance applying device 18 is compressed by the core member 15 in FIG. A resistance force is generated, and this resistance force is experienced by the operator 8 through the support base 7. In addition, when the support base 7 is tilted around the second rotation center axis L2 and angularly deviates from the neutral position, that is, the horizontal state, the elastic member 27 in the second resistance applying device 28 in FIG. Compressed by 25 to generate a resistance force, and this resistance force is experienced by the operator 8 through the support base 7. With these resistance forces, the operator 8 can experience a realistic feeling of resistance against turning when sliding on the snow surface, resistance when performing an edging operation while standing a snowboard, and the like.
[0042]
In the present embodiment, the snowboard sliding screen is projected on the display 1 as a simulated operation, and the support base 7 is set to be used to simulate a snowboard. Accordingly, the operator 8 operates the support base 7 while riding on the support base 7 in a sideways state. Further, when the operator 8 moves the body with the handrail member 11 as a fulcrum, the support base 7 can be reciprocally turned and reciprocated with a large angular width.
[0043]
When performing the pseudo snowboard operation, the operator 8 must ride on the support base 7 in the sideways state. If the operator 8 rides on the support base 7 in a state of facing the display 1 directly, normal snowboard operation cannot be performed. In order to solve such a problem, as shown in FIG. 10, it is desirable to provide a guide projection 72 on the support base 7 for guiding the left and right soles 8 a and 8 b of the operator 8. Since these guide protrusions 72 are arranged in parallel with each other at intervals E1 and E2 corresponding to the lengths of the left and right soles with respect to the direction (arrow D direction) toward the display 1, the operator 8 It is inevitably necessary to ride sideways, and it is possible to reliably avoid a state of riding straight on the display 1. Note that E1 and E2 can be the same value or different values.
[0044]
FIG. 11 shows a modified example of the locking device. In the locking device 32 shown in FIG. 1, the output rod 37 of the locking force applying device 33 is directly pressed against the contact piece 35 via the pressing piece 38. On the other hand, in the locking device 92 shown in FIG. 11, the length of the pressing piece 98 is set long, and is supported by the bracket 97 so as to be capable of reciprocating linear movement, and the pressing piece 98 is directly attached to the contact piece 35. Instead of contacting, the roller 96 provided at the lower end of the contact piece 35 is contacted.
[0045]
In the locking device 32 shown in FIG. 1, the contact piece 35 and the pressing piece 38 are in sliding contact with each other, so that both may be worn and the contact state may be deteriorated. On the other hand, according to the present locking device 92, the pressing piece 98 and the roller 96 are in rolling contact with each other, so that wear is small, and thus a stable operation is guaranteed.
[0046]
FIG. 12 shows another modification of the lock device. In this locking device 102, a cam member, for example, a cylindrical cam 105 fixed to the rotating shaft 22 a or 22 b of the support base 7 is used instead of the contact piece 35 that contacts the support base 7. A cam follower 109 that contacts the cam surface of the cylindrical cam 105 is rotatably attached to the tip of a lever 107 that turns around a fulcrum 108. A roller 96 is rotatably attached to the other end of the lever 107, and this roller 96 contacts the pressing piece 98 of the locking force applying device 33.
[0047]
In the locking device 102, the cam follower 109 fits into the concave portion of the cam surface of the cylindrical cam 105 when the support base 7 is in a horizontal state. In this state, when the maximum locking force is transmitted from the locking force applying device 33 to the lever 107, the cylindrical cam 105 and thus the support base 7 are locked in the horizontal state. On the other hand, when the locking force from the locking force applying device 33 is switched to the minimum value, the locking force to the lever 107 is released, and the cylindrical cam 105 can freely rotate and move. As a result, the support base 7 is locked. The state is released, and it becomes a state that can be tilted freely.
[0048]
Even in this locking device 102, the contact between the pressing piece 98 of the locking force applying device 33 and the roller 96 of the lever 107 and the contact between the cam follower 109 provided on the lever 107 and the cylindrical cam 105 are both rolling contact, so there is little wear. Therefore, stable operation is guaranteed.

As mentioned above, although this invention was demonstrated using some preferable embodiment, this invention is not limited to those embodiments, It can change variously within the technical scope described in the claim.
For example, the present invention can be applied to a simulator for simulating other arbitrary motions limited to snowboard motions. The locking force applying device 33 can be configured by using any force generating device other than the hydraulic cylinder, for example, a pneumatic cylinder, a motor or the like. In the embodiment shown in FIG. 1, a lock device 32 is provided in a rotating system for reciprocatingly tilting the support table 7 around the second rotation center axis L2, and the support table 7 reciprocates around the first rotation center axis L1. No locking device was provided in the rotating system for turning. However, it is needless to say that a locking device having the same configuration can be attached to the rotating system around the first central axis L1.

【The invention's effect】
Simulator according to the present invention According to this locking device, when the state of the support base changes between the locked state and the unlocked state, the magnitude of the locking force gradually weakens or gradually increases over time. As a result, the fixed state of the support base on which the operator is riding does not suddenly come off or go in, but gradually comes off or goes in gradually. Accordingly, since the support base does not swing suddenly when the operator gets on and off, a large load is not applied to the support base and various mechanisms around it, and the durability of the locking device is improved.

[0053]
The present invention in which contact pieces are provided on both sides of the support base According to this locking device, since both sides of the support base can be received by the contact pieces, the support base is more stably locked than when the contact pieces are arranged only on one side of the rotation center axis of the support base. Can be retained. Moreover, the state change between the locked state and the unlocked state can be performed stably.
[0054]
The present invention in which a pair of contact pieces provided on both sides of a support base are connected by a connecting shaft According to this locking device, since the pair of contact pieces installed on both sides of the support base can be driven by only one locking force applying means, the structure becomes simple and further weight reduction can be achieved. Since the support table including the lock device is often supported in a cantilever state, this weight reduction is very advantageous in manufacturing a support structure for the support table. Further, since the pair of contact pieces work together by the connecting shaft, there is no variation in operation between the contact pieces, and thus a stable locked state is always obtained.
